The emitter of the third transistor Q3 is grounded. The collector of the third triode Q3 is connected with one end of a motor or solenoid valve power supply terminal J5. The other end of the motor or solenoid valve power terminal J5 is connected to a power supply voltage VCC2. When the base electrode of the third triode Q3 receives the high-low level change of the slave main control MCU U14, the collector electrode and the emitter electrode of the third triode Q3 are turned off or on, and then the motor or the electromagnetic valve power supply terminal J5 is connected into a circuit or is disconnected. The slave switching circuit may be used to open the breast pump motor and solenoid valve.
The working method of example 3 is:
the mobile phone does not need to be started by a user, the vibration sensor senses the surrounding environment to vibrate, the small night lamp is used as a host, the host main control MCU of the small night lamp receives the vibration signal and sends a control signal to the host switch circuit, and the host switch circuit starts the small night lamp. Meanwhile, the host main control MCU sends out a control signal to the host 2.4G module, and the signal is sent out through an RF antenna connected to the host 2.4G module. The breast pump is used as a slave, the slave 2.4G module receives signals and transmits the signals to the slave main control MCU, the slave main control MCU sends control signals to the slave switch circuit, the motor and the electromagnetic valve of the breast pump are opened, the breast pump works, and the puerpera can directly suck milk. The effect of opening the host and simultaneously opening the slave is achieved.
Since the combination of the master and the slave of the present invention is various and numerous, and cannot be listed one by one, the circuit diagrams of the two embodiments are used to illustrate the specific linking mode of the present invention. However, those skilled in the art will readily recognize that small night lights, milk pumps, breast pumps, cool cups, crying alarms, sleeping posture alarms, wet urine alarms, wet towel heaters, sleep-aiding speakers, cribs, milk mixing kettles, thermometers, wen Nai devices, sterilizing cabinets, sterilizing pans or complementary food machines and the like are all of the prior art, and that many commercial products are sold, and that many related circuit structures have been disclosed in the patent and paper literature, so that those skilled in the art will readily obtain the control circuits for the above devices.
